Try TvRepairKits.com. I just ordered one, I have that same model TV and it is the same problem. I will try to fix it myself as opposed to an expensive service call for repair.

You should have some adjustment for Kine bias and pincushioning. Look for these in settings and readjust the screen

Mitsubishi WS-55807, screen removal / cleaning


Hi, thank you for visit fixya.
Pull out the speaker cover ( slow toward your self).
You will see screws in the middle , take it out ( maybe is 4 o 6 screws), be careful with any wires connect to panel control. Disconnect any connector to panel control. Pull toward your self , slow and slide up . Use a fine brush for best result, use glass cleaner liquid.
Any question, I will be here.
If you need additional help, please send me a picture front tv and I will show the right process.

Thank you

This is a convergence rpoblem that is either bad connections on the pins of the convergence ICs or defective ICs. If you can solder and are comfortable working inside TVs where there are potentially dangerous high voltages, let me know and I'll provide additional details and instructions for fixing this yourself.
